DirectionsUse the bottom piece and the centering tool as a template to mark your1/8" holes for the screws and the pilot hole for the 2-1/4" (58-60mm) hole. The hole for the nail will be drilled later. Pop out and discard the centering tool then rub some beeswax on the insides of the top and bottom piece before assembly to reduce friction. No need to glue it, the mounting screws will hold it all together. Very carefully drill the hole for the nail through the Bee Vac Gate after installation to ensure they line up correctly. Insert a nail (included) through the nail lock and into the hive body to keep the gate from moving when in position. Maybe melt a little propolis in the hive body nail hole to help hold it if necessary.
